[feature] domain block wildcarding (#1178)
* for domain block lookups, lookup along subdomain parts

Signed-off-by: kim <grufwub@gmail.com>

* only lookup up to a max of 5 domain parts to prevent DOS, limit inserted domains to max of 5 subdomains

Signed-off-by: kim <grufwub@gmail.com>

* add test for domain block wildcarding

Signed-off-by: kim <grufwub@gmail.com>

* check cached status first, increase cached domain time

Signed-off-by: kim <grufwub@gmail.com>

* fix domain wildcard part building logic

Signed-off-by: kim <grufwub@gmail.com>

* create separate domain.BlockCache{} type to hold all domain blocks in memory

Signed-off-by: kim <grufwub@gmail.com>

* remove unused variable

Signed-off-by: kim <grufwub@gmail.com>

* add docs and test to domain block cache, check for domain == host in domain block getter funcs

Signed-off-by: kim <grufwub@gmail.com>

* add license text

Signed-off-by: kim <grufwub@gmail.com>

* check order in which we check primary cache

Signed-off-by: kim <grufwub@gmail.com>

* add better documentation of how domain block checking is performed

Signed-off-by: kim <grufwub@gmail.com>

* change
